I'm tempted to pull the trigger on a brand new IC-7700 that's sitting in my local dealer's shelf (as he's offering a good price for it). There is no Icom dealer here in Hong Kong and so if this unit does join the Blown Finals Club I'd have to go through the dealer to have the unit shipped back to Japan and endure all the associated hassle that would entail.
I've read about newer units with the Rev. 12 PA board that seems to have solved the issue.
Does anyone know how to tell what number the PA board would have on any particular unit? Further, does Rev.12 only apply to USA models or to 7700s worldwide? Is there any particular serial number I should look for that may help in the identification of whether the unit is pre- or post- revision? Thanks in advance for any help.
73s Alex VR2WXX Logged. Hi Alex, If the first digit of the country/region prefix in the serial number is 1, the IC-7700 is unequivocally a Rev. 12 is the US/Canada version with S/N of the form 12XXXXX. Other prefixes are 11 for Japan (domestic) and 13 for EU. The PA board is difficult to inspect as it is mounted on the finned heatsink with the fins towards the top.
The PA board is on the underside of the heatsink, so the assembly must be released from the chassis to view the board. Still, if the IC-7700 is new and has a serial number as described above, it will have the Rev.
12 PA and LPF modules. 12 PA uses a single ST Micro STAC2942B (a twin MOSFET device rated for Po = 350W) in its output stage. I have not heard of any Rev. 12 PA failures. I spent the first week of last month in Hong Kong visiting my old friend Johnny VR2XMC, whom you may know.
Johnny and I then travelled to Japan to attend APDXC 2014 and take in some sightseeing (including wonderful Kobe beef!) We were treated to a hands-on preview of the IC-7850. Please visit my IC-7700 page: 73, Adam VA7OJ/AB4OJ Logged.
Had one of the original units (sold it) and never had an ounce of problem with it. I was very careful about the impedances that I fed it into though, and I don't remember using the internal antenna tuner much at all.
When I got the 9100, I was surprised at how much more quickly that internal antenna tuner functioned compared to the 7700's. The 7700 seemed to hunt quite a bit until it locked on. Icom, while they make some nice solid stuff, really blundered on that deal. In typical fashion (ID-51A muffled microphone, ID-5100 no included mounting bracket or hardware and dim display in sunlight, IC-9100 D-STAR as an expensive accessory, etc, etc), took their typical 'screw-you' attitude to existing owners, and quietly redesigned the 7700's PA board without admitting fault in the original.
The radio is really nice, and the new firmware is fantastic. But the rig is getting a bit long in its product lifecycle, and some current products from other manufacturers costing much, much less, are boasting some much better receiver performance numbers. Having owned many of their radios over the years, I've learned one very costly lesson.NEVER buy a brand new Icom design!
Wait until the inevitable bugs are worked out, and only then take your plunge after doing your due diligence in researching everything on the market at your intended price point. You may end up with an Icom, but just make sure it's a VERY informed decision. Personally, I'm done being their cheerleader. Trimble gps pathfinder office. They do make some nice gear, but they're as arrogant as can be, and they'll leave you hanging if you have problems. « Last Edit: December 30, 2014, 09:04:06 AM by K9MHZ » Logged. Well they always say that. Now that the IC7851 is just about to be released I am sure that there will be a new version of the IC7700.
Who is going to buy a IC7700 when for a few more dollars you can buy the IC7851. I would buy a new version of the IC7700 or even the IC7851 if these radios had good TX IMD performance, a transmitter with excellent IMD performance. I would also want a calibrated S-meter.
Reading the specs of the new IC7851 its disappointing to read that they have a 2.8 watt Audio amplifier with 10% distortion. Then you still have to buy a amplifier buffer key box and the ridiculous CT17 RS232 adapter. Why could they not have built all of this required features into the radio. They seem to miss the point of buying such an expensive radio and then having to add 2 silly boxes to have a basic and protected radio.

Its kinda like buying a Ferrari and then be expected to buy new wheels to drive the Ferrari and high speed! If you going to spend 10,000 on a radio I doubt that the extra expensive of adding these features would have added much to the price.
There will be a IC-7750, the discounting of this radio at moment is the clue! The ridiculous CT17 RS232 adapter. I even dragged out my old IC-215 recently, and completely forgot about the external power connector.reverse friggin' polarity. 12 volts.one line is positive, one is negative. 'Hey guys, just for giggles, let's do something fun.let's switch the polarity on a really simple power connector, and watch the cash flow in from the Yankee pigs after they buy lots of our unconscionably priced accessories.
Oh boy, this will be great!' « Last Edit: January 09, 2015, 06:19:37 AM by K9MHZ » Logged Pages: 1.

How to find the genuine hologram label Three types of counterfeit (fake) Icom products Type I Copies of currently produced models (Example) IC-V82, IC-V80(-T), IC-V80E, IC-U80, IC-U80L, IC-G80, IC-80FX, IC-2300H(-T), IC-M304 (Advisory) Purchase only those models with a genuine hologram label. Type II Copies of discontinued models (No production/inventory) (Example) IC-V8, IC-V85, IC-2200H (Advisory) Almost all Type II products are counterfeit.
